Led by the Oregon Primary Care Association, three community health center (CHC) organizations in Oregon developed an Alternative Payment Methodology (APM). Under this APM pilot participating CHCs will receive a prospective payment system (PPS) payment as a capitated equivalent in a per-member-per-month rate for all of their Medicaid patients. Oregon CHC organizations (several clinic sites) implemented Phase I of this demonstration project on March 1, 2013; Phase IIA was implementedon July 1, 2014; Phase IIB on October 1, 2014; and Phase III began July 1, 2015.
